Product Description

This is a strand-specific RNA library construction kit developed for Illumina's high-throughput sequencing platform. It is designed for RNA library construction of 100 pg ~ 100 ng RNA samples, and contains all the components required for RNA fragmentation, reverse transcription (RT), and PCR library amplification. The product is designed for RNA fragmentation by heating, and then reverse transcription with a 3′-N6 Primer with a splice sequence, which relies on the template-switching activity of the reverse transcriptase enzyme to add a splice sequence at the 5′ end of the RNA to produce a cDNA with splice sequences at both ends. AccuNext Sequencing libraries for the Illumina sequencing platform can be obtained by PCR amplification of CDI-joining primers (Illumina, for RNA libraries) (Code No. AG12505, AG12506, AG12507).

This product is easy to operate and can obtain RNA sequencing libraries without the traditional tedious steps of end repair and splice connection; the optimized reaction system improves the library conversion efficiency and is compatible with different template amounts, so that the data obtained from sequencing is highly uniform and has complete coverage; at the same time, the directionality of the template conversion reaction retains the strand directionality of the RNA, so that RNA strand-specific sequencing data can be obtained.

Since rRNA accounts for nearly 90% of the total RNA, it is recommended to remove the rRNA and then construct the RNA library to reduce the proportion of rRNA in the sequencing and obtain more effective data in order to obtain more effective data during the sequencing and to reduce the sequencing cost.

The reaction system of this product has been carefully optimized, please use the reagents provided in this product for RNA fragmentation, reverse transcription and PCR library amplification experiments, and it is recommended that you do not change the dosage and concentration of any of the reaction components, or replace the components in this product with other equivalent products to avoid obtaining bad results. If substitution is required, please verify first.

Product Advantages
1. For Illumina Sequencing Platform: Integrated with Index and Illumina connectors, constructed RNA libraries are ready for NGS sequencing.
2. Wide range of templates: RNA library construction for 100 pg ~ 100 ng RNA; compatible with eukaryotic and prokaryotic RNA samples; degraded RNA can also be successfully constructed, and compatible with RNA samples with RIN values from 2 to 10.
3. Simple operation: RNA sequencing libraries can be obtained without the traditional tedious steps of end repair and junction connection.
4. Accurately recognizes RNA strand specificity: Read 1 reads the antisense strand sequence of the original RNA, and Read 2 reads the positive-sense strand sequence of the original RNA;
5. Stable product performance: Repeatable experimental operations.

Example 1

Use of our products SteadyPure Mag The mRNA was purified using the mRNA Purification Kit (Magnetic Bead Method) (Code No. AG21204). 293T Cell mRNA library was constructed using this product, with 100 pg of RNA template and 19 cycles of PCR amplification, and the results are as follows: Fig. 3-A shows the amplified library products, which are uniformly distributed, with peaks in the range of 200 ~ 700 bp. Figure 3-B shows that there is no product in the negative control without template.

Example 2

The purified 293T Cell mRNA was used as a template for library construction with this product and sequenced using the Illumina NovaSeq 6000 system, and the data are as follows.

Table 1. Key mRNA-Seq data

Example 3

293T Cell mRNA at different concentrations (100 pg and 10 ng) was used as template for reversal and library construction, and two technical replicates were performed and sequenced using the Illumina NovaSeq 6000 system. The correlation of gene expression between the two technical replicates was very high, which indicated that the experiments were reproducible (Figure 4: A is 100 pg and B is 10 ng).

Example 4

100 pg and 10 ng of 293T Cell mRNA were used as templates for reverse transcription and library construction, and sequenced by Illumina NovaSeq 6000 system. After sequencing, the distribution of the sequenced fragments was analyzed, and the results showed that there was no preference for the 5′ and 3′ ends of the fragments amplified by this product, and the distributions were homogeneous (Fig. 5: A is 293T Cell mRNA 100 pg, B is 293T Cell mRNA 10 ng). (Figure 5: A is 293T Cell mRNA 100 pg, B is 293T Cell mRNA 10 ng).
